Concealed Fluorescent Anti-Counterfeit Labels in Printed Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermoplastic materials with anti-counterfeiting designs are not concealed, making them prone to imitation and reducing the effectiveness of the anti-counterfeiting function.
Innovation Solution
A printed article with a base layer, a surface layer, and embedded fluorescent and projection type anti-counterfeit labels that are concealed and only visible when illuminated, using ink printing with light-curing inks and a layered structure to facilitate authenticity identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-counterfeit labels are made visible on the surface of the printed article, then authenticity identification is facilitated, but the labels become easily detectable and imitable
Solution Approach 1:
The patent employs fluorescent materials that change their visual properties based on light illumination. Under normal lighting, the anti-counterfeit labels remain invisible or concealed within the printed article. When ultraviolet or other specialized light is applied, the fluorescent labels emit visible light, revealing their presence and shape for authentication purposes. This dynamic visibility resolves the contradiction by keeping labels concealed during normal use while enabling detection during authentication.
Solution Approach 2:
The anti-counterfeit labels transition from a static concealed state to a dynamic visible state through light interaction. The fluorescent and projection-type labels are designed to respond to specific lighting conditions, changing their visibility status based on the type of light incident upon them. This dynamic behavior allows the labels to remain hidden during normal viewing but become apparent during authentication, preventing easy imitation while maintaining reliability.
2Reliability
If anti-counterfeit labels are concealed within the printed article, then imitation is prevented, but authenticity identification becomes more difficult
Solution Approach 1:
The fluorescent anti-counterfeit labels utilize light-induced color changes to resolve this contradiction. Under normal lighting conditions, the labels remain concealed within the printed article, preventing easy detection and imitation. When ultraviolet or specialized light is applied during authentication, the fluorescent materials emit visible light, making the labels clearly visible and easy to identify. This dynamic visibility maintains concealment during normal use while enabling easy authentication when needed.
Solution Approach 2:
The patent introduces light as an intermediary medium to bridge the gap between concealed anti-counterfeit labels and authentication requirements. The fluorescent and projection-type labels interact with specific light sources (ultraviolet, backlight) to transmit their presence and shape information. This intermediary approach allows the labels to remain hidden during normal viewing but become accessible for authentication through light interaction, resolving the contradiction between concealment and ease of identification.
3Ease of manufacture
If traditional thermoplastic materials with anti-counterfeit designs are used, then manufacturing is simplified, but the designs are not concealed and prone to imitation
Solution Approach 1:
The patent replaces traditional thermoplastic anti-counterfeit materials with fluorescent and projection-type labels that utilize light-induced visibility changes. These labels maintain the manufacturing simplicity of ink printing while adding the concealed visibility feature. The fluorescent and projection labels are integrated into the printed article through standard printing processes, avoiding complex manufacturing while achieving reliable anti-counterfeiting through dynamic visibility control.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The anti-counterfeit labels are effectively concealed within the printed article, preventing easy detection and allowing for simple and convenient authentication by shining light, enhancing the anti-counterfeiting function and reducing the need for molds in production.
Implementation Method 1
The anti-counterfeit label is a fluorescent anti-counterfeit label and is formed via a fluorescent ink printing, such that when a light is shone onto the anti-counterfeit label, the anti-counterfeit label emits a fluorescent light on the printed article
Implementation Method 2
The anti-counterfeit label is a projection type anti-counterfeit label, such that when a backlight is shone onto the anti-counterfeit material, the shape and the profile of the projection anti-counterfeit label shows on the printed article

AI summary
A printed article includes: a base layer and a surface layer, at least one anti-counterfeit label disposed between the base layer and the surface layer. The surface layer and the anti-counterfeit label are formed via ink printing. The printed article is equipped with the anti-counterfeiting function, and the anti-counterfeit label provided can be used for authenticity identification. The anti-counterfeit label is concealed inside the printed article such that it cannot be detected easily. When a light is shone onto the printed article, the anti-counterfeit label shows on the printed article.
